<TD>
<UL>
<LI>bodyp points to a sequence of bytes.
It is <EM>not</EM> a C string (a sequence of characters that is terminated by '\0').
Therefore, do not use the usual C string functions like <CODE>strlen(3)</CODE>
on this byte block.
Moreover, the byte sequence may contain '\0' characters inside the block.
Hence even if a trailing '\0' is added, C string functions may still fail
to work as expected.
<LI>Since message bodies can be very large, defining xxfi_body can
significantly impact filter performance.
<LI>End-of-lines are represented as received from SMTP (normally CRLF).
<LI>Later filters will see body changes made by earlier ones.
<LI>Message bodies may be sent in multiple chunks, with one call to
    xxfi_body per chunk.
<LI>Return
<A HREF="api.html#SMFIS_SKIP">SMFIS_SKIP</A>
if a milter has received sufficiently many
body chunks to make a decision,
but still wants to invoke
message modification functions that are only allowed to be called from
<A HREF="xxfi_eom.html">xxfi_eom()</A>.
Note: the milter <EM>must</EM>
<A HREF="xxfi_negotiate.html">negotiate</A>
this behavior with the MTA, i.e., it must check whether
the protocol action
<A HREF="xxfi_negotiate.html#SMFIP_SKIP"><CODE>SMFIP_SKIP</CODE></A>
is available and if so, the milter must request it.
